STEP 1 DESULPhaTiOn
Detects sulphated batteries. Pulsing current and voltage, removes sulphate from the lead
plates of the battery restoring the battery capacity.
STEP 2 SOFT STarT
Tests if the battery can accept charge. This step prevents that charging proceeds with a
defect battery.
STEP 3 BULk
Charging with maximum current until approximately 80% battery capacity.
STEP 4 aBSOrPTiOn
Charging with declining current to maximize up to 100% battery capacity.
STEP 5 anaLYSE
Tests if the battery can hold charge. Batteries that can not hold charge may need to be replaced.
STEP 6 rEcOnD
Choose the Recond program to add the Recond step to the charging process. During the Recond step
voltage increases to create controlled gasing in the battery. Gasing mixes the battery acid and gives
back energy to the battery.
STEP 7 FLOaT
Maintaining the battery voltage at maximum level by providing a constant voltage charge.
STEP 8 PULSE
Maintaining the battery at 95–100% capacity. The charger monitors the battery voltage and gives a
pulse when necessary to keep the battery fully charged.
